Im not yet sure on price, so far the only company to get back to me wants me to order at least 50 of the.. so I'm going to look for another company and maybe find out how many people want them..
A speed test on the BCM card wont be very accurate yet since I have no antennas plugged into it
I doubt you will find a people to make you less than a bulk amount. These custom adapter designs won't be profitable unless you make these amounts. That being said... I'm down to buy a few myself. Soldering with coaxial cables can be finicky as there's a dielectric that's pretty important to signal transmission between the inside conductor and the shielding (ground in most instances). Just soldering might result in incorrect impedance matching and could lead to poorer signal ultimately. Anyway, let us know if you've got any progress with your companies.
